Hi in order to install the OS you need to have the SCSI drivers on a floppy disk and then, when prompted at the start of the installation process, press F6 (“Press F6 to for additional drivers) and then provide the given driver for the SCSI.
So go to the SCSI manufacturer site, search for the drivers and create the diskette first and then follow the procedure.
It is also possible you may need to configure the RAID first. If that is the case you should see a prompt while booting to entry the RAID configuration utility. If you see that prompt select that option and set up the array first. Then you can reboot and start the installation again and you should see the disks.
Actually, the correct answer (no offense to anyone) is a bit of both:
You will need to have your RAID array configured and (preferably) built/created in the HBA BIOS prior to attempting an OS install ** AND ** for Win2K3, the use of a floppy drive is hard coded into the OS: direct attached, USB are OK; USB flash emulating floppy will not function reliably.
For faster motherboard/processor combos, start pressing “F6″ BEFORE the prompt appears, otherwise the drivers will load too late and will not apply correctly (i.e.: if you see the F^ prompt message, you’ve waited too long).
